Product details:

Product Description Our Pit Pillow is an extra soft gymnastic mat with very loan density foam in a denim cover. It is designed to mimic the feel of a mat on a loose foam pit and be placed on another foam or air mat. The 3x4x8 Pit Pillow is NOT intended for use on hard surfaces or alone. It has Hook and loop on all sides so that several can be connected end-to-end side-by-side or stacked vertically. The Hook and loop also allows the Pit Pillow to connect to our other smart mats such as the Baby Bear or Mama Bear mats.
